OPHTHALMIC MOUNTING.

Original No. 1,293,232, dated February 4, 1919, Serial No. 265,139,,fi1ed December 3,1918. Application for reissue filed May 17, 1920. Serial No; 382,122.

To allwhom it may concern Be it known thatI, FREDERICK A. STE- VENS, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Ophthalmic Mountings, of which the followin is a specification. 1

y invention relates to. that class of mountings in which an auxiliary rim is employed.

The principal objects of my invention are to provide an inexpensive and efiicient means for assembling theauxiliary rim to the skeleton rim and for securely retaining the assembled parts while in use; and to attain theseends in a non-expensive structure. I

To the above ends essentially my invention consists of such parts and combinations of parts as fallwithin the scope of the appended claims.

In the accompanying drawings which form a part of this invention, and wherein like reference characters indicate likeparts throughout theviews;

Figure l is a rear elevation of a pair of spectacles embodying my invention,

Fig. 5, a section on line 55 of Fig. 4,

Fig. 6, a section on line 6-6 of Fig.- 1, and

Fig. 7, a similar section showing a modified form of eye wire best adapted for eyeglasses.

My invention in its illustrated embodi ment is applied to a spectacle frame. skeleton of the latter comprises the bridge 8 fast to the central portions of the wires 9 which are intended for subsequent bending into circular rims. This stage of construction is shown in Fig. 2. The wires 9 are sub} stantially flat or oblong in cross section.

- .;i -iee eela Each wire isprovide'd intermediate its width on one face with a longitudinal rib ll'preferably acute angular in cross section. One face 12 of therib is vertical, and the Other The In constructing spectacles the rims are first applied to the wires. Therims, in the present instance consisting of two sections 15, are preferably composed of zylonite, celluloid, or other non-metallic material. One such section is shown in Fig. 4. This is provided in its rear side with a longitudinally disposed rectangular oblong slot'17 extending beyond the center of the rim through a major' portion of its thickness or depth dividing the rim into wings or sections 18 and 19. Extending into the wing 18 from the slot 17 is an annular recess 21, angular in cross section, bounded by a vertical wall or face 22 and an inclined wall 23. In the outer face of-the wing or tongue 19 is an annular groove 25, preferably V shaped in cross section.

The wires 9 and rims 15 are bent into circular form before receiving the lenses 27, whose margins enter the grooves 25. Each section 15 has notches 29 and 30 at the ends of the wing 19 to accommodate end pieces 31 soldered or otherwise fixed to the ends of the wires 9. The end pieces 31 are attached together by screws or pins 33; and the-temples 34- are connected as usual.

The parts are assembled, after the rims and wires have been bent into circular form,

thus. Each annular metallic rim 9 is inserted edgewise or laterally into the annular slot 17 ofthe annular rim. By reason of its resiliency, the section 19 is adapted to yield sufliciently to permit the rib 11, which is being forced into the slot, to pass into its recess seat 21 whereupon the section 19 returns to its natural position. The cross section of the slot 17 is substantially the same asthat of the wires 9, so that the metallic rim that is seated in the slot occupies substantially all the space of the slot. The inclined face13 of the rib 11 facilitates introduction the wire, while the face 12 tends to prevent separation of the rims, the faces 12 and 22 coacting to lock the rims together. 5 I v i introduction maybe facilitated by shaping the wire 9 as shown in Fig. 7. That is, one lateral margin is reduced, as at 35, so that its inclined "upper surface 36 merges into the surface 13.

; ew -a e e nre p e e the 1 use of screws, clips or other additional means for securing the rims together in locked relationship is done away with, and the necessity for either swaging the metal to conform to the shape of the non-metallic rim or of pressing the non-metallic material into firm contact with the metallic rim is entirely eliminated. As, therefore, neither the metal nor the non-metallic material is subjected to permanent strain as a result of the assembling operation, there is no tendency for the non-metallic material to shrink away from the metal rim, so that if the nonmetallic rim is originally cured to the proper degree before the rims are assembled, it will remain in place upon the metallic rim, exactly in position as originally mounted thereon. A very efficient and attractive ophthalmic mounting is thus provided.

The foregoing description is directed solely toward the construction illustrated, but I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and 'limited only by the terms of the appended claims.
